Pressure-Regulating Valves

Pressure-Regulating Valves

Reduce inlet pressure to a lower outlet pressure to protect sensitive equipment

Pressure-Relief Discs

Pressure-Relief Discs

Rupture at a set pressure or temperature to vent fluid and gas and protect machinery; one-time use

On-Off Valves

Start and stop flow through a line

Directional Control Valves

Directional Control Valves

Manage the flow of fluids to move equipment in air- and hydraulic-powered systems

Diverting Valves

Diverting Valves

Redirect flow between ports

Mixing Valves

Blend hot and cold water, steam, or oil to maintain a set outlet temperature and prevent scalding

Power Transmission

Safety Lockout Valves

Safety Lockout Valves

Prevent accidental start-up when servicing equipment

Facility and Grounds Maintenance

Air Admittance Valves

Air Admittance Valves

Allow air into drain, waste, and vent systems so you don't have to vent plumbing to the outdoors
